When the Police arrive after the 'house smashing' scene one of the vehicles is a Bedford CF with a 1976 registration plate. Whilst the vehicle was available in 1976, the model shown is a post 1980 face lifted version with a plastic radiator grille.
Telltale modern features on the terraced housing, e.g. uPVC windows and the post-1991 dialling code for Sheffield on a poster on window, when setting is intended to be 1977. Also distinctly visible are the modern tram tracks which were laid in 1994.
